Washington State I-502 prohibits home cultivation of recreational cannabis. Kirkland residents cannot legally grow marijuana at home. Only registered medical patients may grow limited plants under RCW 69.51A.
Unlike some states with legalized recreational cannabis, Washington State under Initiative 502 (I-502, passed 2012, codified at RCW 69.50) does NOT permit home cultivation of marijuana for recreational personal use. All recreational cannabis sold in Washington must come from Washington State Liquor and Cannabis Board licensed producers and retailers. Kirkland residents who grow cannabis plants at home for recreational use are in violation of state law regardless of quantity. Limited exception exists for qualifying medical cannabis patients with a valid authorization from a healthcare provider who are registered in the Washington Department of Health Medical Marijuana Database. Registered patients may possess and grow up to 6 plants and possess up to 8 ounces of usable marijuana (or higher amounts up to 15 plants and 16 ounces if a healthcare provider determines medical need). Cooperative grows of up to 4 qualifying patients may exist under RCW 69.51A.250 with strict registration and location requirements. All home cultivation must occur in a space not visible from public view.
Unlawful manufacture of marijuana under RCW 69.50.401 is a felony offense. Medical patients exceeding plant limits lose protections. Unregistered grows may trigger civil and criminal penalties.
